Universal Electrical Connection Device for a Battery Box and/or a Battery

A connection device for a battery charging system housed in a housing case (10) of a headlamp comprising:

• a connector (60) provided with three electrical contacts arranged linearly and further comprising two flexible jaws having at their end a cylindrical surface intended to clip onto a housing case (10) of a battery (200);
• in which said connector comprises a first (61), a second (62) and a third (63) electrical contact arranged linearly and the second contact (62) being arranged at an equal distance from the two jaws;
• and
• a housing case (10) for a battery (200) having two left and right side faces each comprising a recess with a hooking profile (45, 46) configured for a corresponding jaw of said connector (60), said housing case (10) having a first electrode terminal (41), a second electrode terminal (42) and a third electrode terminal (43) arranged linearly and configured to allow an electrical connection with each of the three contacts (61, 62, 63) of said connector (60);
• and
• wherein the profile of each of said recesses comprises two substantially flat surfaces substantially forming a re-entrant angle, and which are connected by means of a semi-circular groove 45b whose generating axis is parallel to the upper edge of the left lateral face, wherein said semi-circular groove (45b) provides a support line for said cylindrical surface of a corresponding jaw, so as to allow clipping of the connector;
• wherein the first and third electrical terminals (41, 43) are dedicated to the transmission of a first electrical voltage and wherein the second terminal (42) is located at an equal distance from the left and right attachment profiles so as to allow connection of the connector from the right or from the left and is also dedicated to the transmission of a second voltage.
